As Fig. 2, shown in Figure 3, the utility model comprises casing (1), braces (2), mobile phone (3), circuit board (4).Casing (1) is made with rigid plastics, and its effect is to hold each parts of the present utility model, forms an integral body.Braces (2) is made with soft fabric, and two is installed on two side plates of casing (1), and effect is to be easy to carry.Mobile phone (3) is to replace with existing cell-phone unit, on receiver SH in the main circuit is installed, transmitter S, send speech audio amplifier SF, audio frequency/Pulse Dialing device FH, and added a button key K1, each circuit output lead of this mobile phone (3) is connected on the interior circuit board (4) of casing (1), casing leaves the space in (1), make mobile phone (3) when not using, can put into casing (1), circuit board (4) is installed in the casing (1), circuit board is equipped with on ﹠ off switch K6 on (4), K2, linked switch key K4, K5, jack CK, output line W1, W2, two Battery pack DC1 in the main circuit in addition, DC2, transformer B, capacitor C 1 and C2, electric bell DL, magneto F is installed in the casing (1), wherein the crank of magneto F is contained on the side plate of casing (1), and on ﹠ off switch K3 and crank link.

Contrast Fig. 1 and Fig. 3, set up following circuit and element: battery pack DC2, audio frequency/Pulse Dialing device FH in the utility model, send speech audio amplifier SF, audio signal generator YP, change over switch key K6, on ﹠ off switch K2, linkage switch key K4, K5, capacitor C 2, by the conversion operations of each key, will form following each functional circuit independently:

1, transmitting circuit: form by interlock key K5, magneto F, interlock key K3, outwards export 15-25 week by output W1 and W2,90 volts of following ringing signals.

2, automatic telephone signaling circuit: by interlock key K4, K5, interlock key K3, audio frequency/Pulse Dialing device FH form, by output W1 and the outside output audio of W2/pulse automatic telephone dialing signal.

3, trusted circuit: form by interlock key K4, K5, capacitor C 2, interlock key K3, electric bell DL.Import outside ringing signal by output W1 and W2, trigger electric bell DL and send the tinkle of bells.

4, PAC circuit: form by interlock key K5, interlock key K3, capacitor C 1, the output winding of transformer B, receiver SH,, make receiver SH sounding by output W1 and W2 input external audio signal.

5, telecommunication circuit: by battery pack DC1, change over switch key K6, button key K1, transmitter S, send speech audio amplifier SF, transformer B, capacitor C 1, interlock key K3, interlock key K5, receiver SH to form.Sound converts audio electrical signal to through transmitter S, amplifies through sending speech audio amplifier SF, carries out impedance matching by transformer B, audio electrical signal is exported this electric routing battery group DC1 power supply to the outside by output W1 and W2.
